Abstract: A surgical access device includes a cannula having a variable length. The cannula may include a shaft assembly including an outer shaft, an intermediate shaft disposed within and longitudinal slidable relative to the outer shaft, and an inner shaft disposed within and longitudinal slidable relative to the intermediate shaft. The shaft assembly is movable between an unextended position, a fully extended position, and a semi-extended position between the unextended and fully extended positions. The cannula may include a shaft having annular folds formed therein. The annular folds are axially movable relative to each other such that the shaft is longitudinally movable between an unextended position and a plurality of extended positions.

Abstract: A method of forming a balloon for a surgical access device includes positioning a molding material into a channel defined in a first mold half of a mold and mounting a second mold half onto the first mold half to cover the channel and form a cavity within the mold. The first and second mold halves each includes vent holes extending therethrough that are in fluid communication with the cavity. The method also includes expanding the molding material to conform to the shape of the cavity to form a balloon including protrusions extending radially outwardly therefrom. The protrusions are formed by engagement of the molding material with the vent holes.

Abstract: A surgical robotic system includes a surgical robotic arm and a surgical instrument configured to couple to the surgical robotic arm. The surgical robotic arm has a housing and a pulley rotationally supported in a distal end portion of the housing. The surgical instrument has a housing and a gear rotationally supported in a proximal end portion of the housing thereof. The gear is configured to operably couple to the pulley of the surgical robotic arm to transfer rotational motion from the pulley of the surgical robotic arm to a functional component of the surgical instrument.
